DZ23C2V7-E3-18

Overview

The DZ23C2V7-E3-18 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 2.7 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 20 μA at 1 V. Dynamic resistance is specified at 83 Ω under these conditions. Power dissipation reaches 500 mW when mounted on an FR-4 board with the recommended footprint, supporting an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation within the E24 standard grading system.
• Features high electrostatic discharge (ESD) protection capabilities exceeding 8 kV via human body model standards.
• Designed for compact surface-mount integration using the SOT-23 package configuration.

Applications

• Voltage reference circuits requiring low-voltage stability
• Protection against overvoltage transients in signal lines
• Biasing networks for small-signal semiconductor devices

Procurement Notes

Verify that the ordering suffix matches the required reel size and minimum order quantity specifications. Confirm RoHS compliance status aligns with project requirements. Ensure the component designation corresponds exactly to the commercial grade variant rather than the automotive qualified version. Cross-reference the manufacturer part number with distributor catalogs to validate availability and authenticity before finalizing supply chain agreements.

Selection Notes

Select this component when a precise 2.7 V regulation point is necessary within tight spatial constraints defined by the SOT-23 form factor. Evaluate the thermal management requirements carefully, as power dissipation drops significantly if the device is not mounted on a PCB with the recommended soldering footprint. Consider the negative temperature coefficient inherent to low-voltage Zener diodes when designing circuits exposed to wide ambient temperature variations.

Part Context

This device belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series encompasses a broad range of nominal voltages from 2.2 V to 75 V, all sharing common packaging and electrical characteristics. The specific part represents the lower end of the voltage spectrum, utilizing a 5 mA test current parameter distinct from higher voltage variants in the same family.

Replacement Considerations

Direct substitutes include other DZ23 series parts with identical voltage ratings but different packaging suffixes, such as the -08 variant. Cross-brand replacements must match the 2.7 V nominal voltage, SOT-23 package dimensions, and equivalent dynamic resistance values to ensure circuit compatibility without redesign.
